Application filed June 4,

Ihis invention relates to a device for the prevention of the theft ofautomobile inacliiiies and it consists in the novel features hereinafterdescribed and claimed.

An object of the invention is to provide an alarm device adapted to beapplied to an automobile machine and which includes a casing adapted tobe mounted upon the drive shaft housing and having` spaced gongs mountedtherein. A clapper is pivotally mounted in the casing between the gongsand an end Aportion thereof extends into the housing of the drive shaft.The drive shaft is provided with outstanding lugs adapted to engage thestein of the clapper thus causing the clapper to sound the gong when theshaft is rotated. A clapper controlling key is slidably mounted in thetop of the casing and is connected with the clapper and may be used forlifting` or elevatingl the clapper so that thelower end of the steinthereof will be beyond the path of movement of the lugs upon the driveshaft. A locking means is provided for holding` the said key in anelevated position.

rlhe parts and features are so arranged that when the driver of amachine leaves the saine he may depi'ess the clapper controlling keythus lowering the clapper and the clapper controlling` key may be lockedin a lowered position hence should an unauthorized person attempt toremove the machine the lugs upon the drive shaft will strike the stem ofthe clapper and vibrate the same whereby the gongs are sounded.

ln the accompanying drawing:

Figure 1 is a vertical sectional view of the device for the preventionof theft of automobiles.

Figure 2 is a top plan view of the saine.

Figure 3 is a detailed sectional view through the upper portion of thesaine.

The device for the prevention of theft of automobile machines comprisesa casing 1 having a cover 2 mounted thereon and which is provided with anumber of openings 3. The casing` 1 is adapted to be mounted upon theshaft housing of the machine and is provided at its bottom with anopening 4 which registers with an opening 5 in the shaft housing. Thedrive shaft 7 is journaled in the housing in a usual manner and isprovided at its side with -outstanding lugs 8. A standard 9 is mountedin the casingl 1 and spaced gongs 10 mounted upon rods 11 are alsolocated within the casing. A bar 1926. Serial N0. 113,781.

is pivotally mounted upon the standard J and may be moved verticallywith relation to the standard. The clapper consists of a stem 12 havinga slot 13 which receives a stud 14 mounted upon the standard and thelower portion of the stem 12 passes through the registering opening f1and The clapper is provided at its upper emi with a head l-whieh isdisposed between the gongs 10. A rod 16 passes through the centerof thecover 2 and is provided at its lower end with a cage 17 which receivesthe upper portion of the stein 12 of the elappei' and the head thereof.The cage is provided'at its side with openings 18 through which the headmay pass and in order to neru'iit the head to strike the gongs and soundthe same. The rod 1G is provided in the vicinity of its upper end withspaced blades 18 which are slidably received in a groove 19 provided atthe central portion of the cover 2. A collar 2O is mounted upon the rodand is located under the cover and may engage the coverto prevent therod from being withdrawn from the cover and the easing. The rod providedat its upper end and at a point above the cover with a. handle 2l. Alock bolt 22 is housed in the intermediate portion of the cover and maybe moved by insertinga key (not shown) in a barrel 23 whereby the lockbolt may be interposed in the space between the blade or against theupper edge of the upper blade to hold the rod in a lowered position andwhereby the upper edge of the slot '13 rests upon the stud 1st. At thistime the lower end of the stem 12 is disposed in the path of movement ofthe lugs 8 carried by the drive shaft.

In the event that the drive shaft should be rotated the lugs strike thelower end of the stem and swing the clapper upon the stud whereby thehead 15 thereof passes through the opening 18 in the cage and strikesthe gongs 10. The sound passes through the openings in the cover 2. andconsequently a warning is given that the automobile machine is beingstarted or operated by an unauthorized person.

When the owner of the machine desires to use the same he uses hisprivate key for lue turning the barrel of the lock whereby the y bolt iswithdrawn from between the blade of the rod and said rod is liftedwhereby the stem of the elapper is elevated so that its lower end isdisposed beyond the path oi' movement of the lugs carried by the driveshaft. Therefore as the drive shaft rotates the said lugs will clear thelower end of the stem of t-he clapper and the gongs Will not be sounded.

lVhen the device is locked any attempt to start the car will set thealarm going and if desired the device may be provided with an electricconnection (not shown) which vvill subject the unauthorized driver to anelectric shock. Any type of lock may be eniployed for holding and movingthe bolt which engages the blades of the rod,

From the foregoing description and in conjunction with the accompanyingdrawing it will be seen that a device for preventing the theft of anautomobile machine of simple and durable structure is provided and thatthe same may be conveniently used for assuring the protection of themachine in the absence of the authorized owner thereof.

From the foregoing description of the construction of my improveddevice, it Will be seen that I have provided a simple, inexpensive andefficient means for carrying out the objects of theV invention and whilel have particularly described the elements best adapted to perform thefunctions set forth, it is obvious that various changes in form,proportion and in the mino-r details of construction may be resorted toWithout departing from the spirit or sacrificing any of the principlesof the invention.

Having described the invention, what is claimed is:

l. A device for the prevention of the theft of an automobile machinecomprising a casing having openings and adapted to be mounted upon thedrive shaft housing` of the automobile machine, lugs mounted upon thedrive shaft of the automobile machine, spaced gongs located in thecasing, a clapper member pivotally mounted in the casing at a pointbetween the gongs and having an end portion passing through the bottomthereof and the side of the drive shaft housing, the lower end of theclapper normally lying in the path of movement of the lugs upon theshaft and means for liftingthe clapper.

2. A device for the prevention of theft of an automobile machinecomprising a casing adapted to be applied to the drive shaft housing ofan automobile machine, lugs mounted upon the drive shaft of theautomobile machine, spaced gongs located in the casing,y a supportingstud located in the casing at ay point between the gongs, a clappcr stemhaving a slot which receives said stud said stem passing through thebottom of the casing and the housing, a head carried at the upper end ofthe stem, a rod slidably mounted in the casing means for holding the rodat an adjusted position and a cage carried by the rod and which receivesthe head of the clapper.

23. A device for the preventioi'i of theft of automobile machinescomprising a casing adapted to be applied to the drive shaft housing ofthe machine, lugs carried by the drive shaft of the machine, spacedgongs located in the casing, a stud mounted in the casing, a clappershank having a slot Which receives said stud said shank entering thedrive shaft housing, a rod slidably mounted in lthe casing, a cagecarried at the lower end of the slot and receiving the upper portion ofthe clapper and having openings through which the upper portion of theclapper may pass, said rod being provided at its side with spaced bladesand a locking bolt movably mounted in the casing and adapted to en gagethe edges of the blade.

ln testimony whereof I atlix my signature.
